Nearly all large cities today are large cities because they historically were one, leading to economies of scale in infrastructure and agglomeration economies in the production and exchange of goods and services. Ease of sea access is not a major determinant of a city's growth & prosperity today.

Many cities historically grew around ports due to the labor intensity of break-bulk shipping and the difficulty and expense of overland goods transport but modern container ports require relatively few employees and can easily move freight intermodally. The old piers in London and Hamburg and New York and San Francisco and their adjacent factories have all been redeveloped, and the working container ports have all relocated away from the city center to places where rail & highway access is easier, to places like Newark, Oakland, and Felixstowe.
